LABOR LAWS AND CORPORATE INVESTMENT
研究发现，在没有工作权利法的州，工会化企业的资本支出比其它企业低约4个百分点，通过俄克拉荷马州通过工作权利法的自然实验和工会认证选举的断点回归设计验证了这一结论。
Abstract In the United States, the costs of unionized labor are higher in states without right‐to‐work (RTW) laws. I show that unionized firms located in these states invest less. These firms have about 4 percentage point lower capital expenditures (normalized by net property, plant, and equipment) than other firms. I confirm these findings by examining a natural experiment created by the adoption of RTW laws in Oklahoma and examining union certification elections using regression discontinuity design.
